Susan, when we used Hearme, we were in a room that was pretty well hidden from those outside Mudcat and there was no question of a room rating. There was also no ability to admin a room although I can't remember there ever being a problem there.The Paltalk rooms, particulary the open ones did present new problems, the room rating being one of them. I still do not know a correct answer to this one and I don't believe we really fit into any category - I'd guess something like a PG rating would suit us best.
The only thing I can say is that in my experience, people both from Mudcat and from outside that genuinely want to use the folk rooms seem to be reasonable and would not want to cause offense although handling a problem regarding under 18s in an Adult room could be difficult as I don't think they are really supposed to be there according to Paltalk's rules - I don't think the signing in would be allowed.
